无法使用 jquery 获取悬停 svg 元素的 id

Question

I want to get the id of the svg-element (text) which has been hovered. The HTML:

<svg class="compass-svg" width="200" height="200">
     <text id="textN" x="93" y="55" fill="#000">N</text>
     <text id="textE" x="145" y="105" fill="#000">O</text>
     <text id="textS" x="95" y="158" fill="#000">S</text>
     <text id="textW" x="40" y="105" fill="#000">W</text>
</svg>

This is the javascript code:

$('text').hover(() => {
    //this is not working
    console.log($(this).attr('id'));

    //this is also not working
    console.log(this.attr('id'));

    //I've also tried this
    console.log(this.id);
});

When I hover for example the first text element it should write 'textN' to the console.

Answer 1

Use event.target.id , here is an example:

 $('text').hover((e) => { //this is working console.log(e.target.id); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <svg class="compass-svg" width="200" height="200"> <text id="textN" x="93" y="55" fill="#000">N</text> <text id="textE" x="145" y="105" fill="#000">O</text> <text id="textS" x="95" y="158" fill="#000">S</text> <text id="textW" x="40" y="105" fill="#000">W</text> </svg>

Answer 2

You are using an arrow function that changes scope inside it. If you use function keyword, you can get the values normally:

 $('text').hover(function() { // This will work console.log($(this).attr('id')); // This will also work console.log(this.id); });

 .as-console-wrapper { max-height: 85px !important; }

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <svg class="compass-svg" width="200" height="200"> <text id="textN" x="93" y="55" fill="#000">N</text> <text id="textE" x="145" y="105" fill="#000">O</text> <text id="textS" x="95" y="158" fill="#000">S</text> <text id="textW" x="40" y="105" fill="#000">W</text> </svg>

$('text').hover(function () {

    console.log($(this).attr('id'));
